Application filed August 12, 1812. .Serial No. 1113,69.

To all whom it may concern:

.Be it known that l, 'Encinas Hoen.. l l

In carrying t e invention into eiect as Pennini, a subject of the' King of Great Britain and ireland, residing at 44 Mortlake road, Kew Gardens, in the county of Surrey, England, consulting engineer, have invented a certain new an Useful Carbur vter, of which the following is a specification.

Thisinvention relates to carbureters :for use with internal combustion engines and for other purposes and has for its objge'ct to' provide simple and eietive means for controlling the su ply of air to the carburoter and the supp y of combustible mixture therefrom, while at the same time insuring 'that the mixture of air and vapor is uniform.

ifiocording to the invention a closely wound helical spring closed at each end is provided andthe air, on its entry into the carburetor, is' caused tospass between and into-the coils of vthe spring. `Vlitbin the spring theyet for the hydrocarbon is disposed. lhe combustible mixture of hydrocarbon vapor epd air' is' then .passed outwardly between. the coils of the spring at the farther end there- -isf, and is led from the carburetor for use.

` The sprin' is mounted under the action of Suitable con rolling means to vary the reiation of the coils oy which it may be extended to increase the area of the space or passages between its respective coils through which the air passes inwardly or the combustible mixture outwardly.

`The passage o the air between the .coils or" the spring serves to break it up or divide it et the moment that it is brought into con-A .tact with the hydrocarbon vapor -for ininture therewith, and a similar edect of intimate division or admiiture is .produced upon the combustible mixture as it leaves the spring. i n

Any convenient number of such springs may be provided in the carburetor and where more than one is used they may be provided with separate or common controlling means as desired.

The applicationof the invention .is illustrated in the accompanying drawings, in which- A f Figure l is a sectional elevation of acarbureter having a single helical spring. Fig. 2 is a sectional elevation of a carbureter having three helical springs, taken on the line ai :u of Fig. 3. Fig. 3 is a plan of the carburetor represented in Fig. 2, thecover plate bei removed.

illustrated in Fig. l, the carburetor casing is constituted by two partsa b adapted to be fitted together and eachv having an enlarged portion with alaterally disposed pas- Sagem.'v aperture al b1. The part a' is advantageously integral with they oat chamber o which is of any convenient construction. At its upper end the part a is screwthreadedon the exterior to engage with an internal screw-thread on 'the part b. A tube d, within which the springis slidably carried and having a shoulder or flange at its .u per. end, is fitted in the part a andfsecure' in position by the screwing home of thel part b,.which is provided witha suitable shoulder to outrage the shoulder or lia nge of the tube d. lock-nut is preferably pro'- vided to maintain the parts a b in the adjusted relative positions.

The helical spring e is screwed or otherwise secured within a .recess at the upper' end of a plug a2 which 1s seated at the lower end of the part a and secured in position by a cap a8 screwed upon its proJecting extremity. At its' upper end the spring is screwed into or otherwise secured to a cap f carried by a rod f1 or wire which lpasses through a cap b2 at the upper end of the 'part b and is connected to suitablel means by float chamber. The air or gas is adinitte'df to the carbureter by the inlet aperture al and passes inwardly between the coils of the sprin the spring being extended, as determine and' then mixing with the hydrocarbon vapor 'from the nozzle passes upwardly along the spring and outwardly between the coils of the spring adjacent thecap 'f and In the construction illustrated in Figs. 2 andi acylindrical carburetor casing is rovided having two transverse partitions 1 71,2 in which the tubes .d for the several springs e are carried, thej-tubes passing tbroughfhQles in the upper partition h1 and oo h away from the 'carburetor by the exit aperture b1..
